York, have invented new and useful Improvements in Single-Trigger Mechanism for Double-Barrel Guns, of'whic'h the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

ThlS invention relates to improvements in single-trigger mechanism for double-barrel breech-loading guns.

The primary object of these improvements :5 is to prevent the accidental or premature firing of either of the barrels of t e gun by the recoil or rebound incidental to the discharge of the other barrel and to enable the operator to control the operation'of the hammers as I positively and safely as though each hammer were controlled by aseparate trigger.

Another object is to provide means under the control of the I operator whereby the -same (either right or left hand) barrel may be fired first after each successive breaking and closing of the gun.

Referring to the drawings, Figure 1 is a top plan of my improved trigger mechanism,

showing the parts in their normal position 30, assumed when the gun is closed and both hammers ready to be fired. Fig. 2 is a sectional view taken on line 2 2, Fig. 1. Fig. 3 is a sectional view similar to Fig. 2, the hammer, trigger, and sear-operating-pawl being shown in the fired position. Fig. 4 is a side elevation of the parts seen in 'Fig. 1, the right-handhammer and its sear being shown in the fired position, while the left-hand hammer is m the position to be fired, the position of the trigger being normal. Fig. 5 is an elevation similar to Fig. 1,- showing the hammers, sears, trigger, and pawl in their fired positions. Fig. 6 is a sectional view similar to Fig. 2, except that the sear-operating 4 5 pawl is shown in section and the mainsprings and scars are removed. Fig. 7 1s a perspec-- tive view of a weighted sear-o crating pawl. F1". 8 IS a pers ective view 0 the scars and th e shoulder w 'ch is movable into and out of operative engagement with the scars.

Similar reference characters indicate correspondmg parts in all the views.

In carrying out the objects of th tion we provide a trigger-plate 1, up is mounted a trigger 2, hammers a1 springs 3 and 4, sears 5, and a cock '6, all of which parts perform thc functions andare adapted to coopei the remaining features of our invent ently described.

The trigger 2 is pivoted at 7 bet front and rear ends and is provide forwardly-extending arm 8, to Wll] cured one end of a light spring 9, 1 end extending rearwardly beyond 1 7 for carrying a weighted sear-r pawl 10. This trigger 2 is located tially midway between the hamme is provided with a rearwardly-exten 11, which is adapted to engage a b 12 for limiting its upward move? rather for limiting the rearward it of the finger-piece of the trigger.

10 is pivotally mounted upon the and is provided with teeth or shot which are movable into and out o. ment with similar teeth or shou formed, respectivel ,upon the rear e1 sears 5, said paw being weighted manner that the recoil of the gun with its own inertia coact to se shoulders 14 and 15in other wor s is automatically forced to its inopei sition when either of the barrels is di: The purpose of this weighted pawl vent the accidentalor premature I of one of the barrels at the time of of the other and also to'prevent the neous discharge of both barrels.

It is well known that when the g the operator is voluntarily pullmg t. and that the recoil rearwardly and forwardly are almost instantaneous pull on the trigger, so that when takes place the finger-piece of the t codes from the finger of the operato: mits the trigger to instantly assunt mal position, and the rebound bell taneous produces an involunta the trigger by the operator, w cause the firing of the other barrel i for the fact that the pawl is instant to its inoperative position at the re account of its inertia cannot possi 11 takes place. In order that 1 against the accidental dis- 111 may be further carried out, pawl with a second tooth or hich automatically interlocks 20th or shoulder 17 of a springshoulders being adapted to inch other when the recoil takes he rebound will not affect the of further explanation of this t may be stated that the teeth and 15 of the pawl and sears, re so positioned relatively to .t when the involuntary pull :r takes place which would reder 16 from the detent-shoulllder 14 is elevated abovethe D that they cannot interlock r until the pull upon the trigwhereupon the tooth 14 drops position for engaging and opr when the trigger is voluntahis is an important feature of and it is apparent from the .on that the time between the und of the gun upon the. dis- 1ort to permit the pawl 10 to erative position in time to be re involuntary pull upon the he rebound. which is secured at one end engages a shoulder 19 upon side of its pivot and serves to its operative position when holding engagement with the 7, this spring being very light, 3 little resistance as possible it of the pawl to its inoperative ily function of this spring bepawl to its position for enilders of the sears. the sear of the fired hammer ere with the operation of the )ther hammer,we provide each s with a cam-face or shoulder upon the forward end of the hammer is released and holds the sear in its elevated inoper ut of the path of movement of 1 being operated to trip the 1e mainsprings 4 operate their imers and sears, one arm of ng connected to a stirrup 21, heel of the hammer, and the ges the sear at the rear of its 1e point of the sear into holdt with a sear-notch 22 of the :ars being pivoted at 23 to the ies desirable to fire the same r each break and close of the refore provide means to operatively connect the trigger with each of the sears separately from the other sear, said means consisting in this instance of a laterally-movable shoulder 24, which is'adapted to be moved manually between a shoulder 25 on the trigger and a similar shoulder 26 on the sear, each sear being rovided with one of these shoulders 26, wlnch project toward each otherrfrom the heel of the sear. Any desired means may be employed for moving this shoulder'24 laterally into and out of registration with the shoulders 26; but we have here shown said shoulder as mounted u on the in 12, which is movable endwise or lateral y in suitable bearings provided in the trigger-plate, the opposite ends of said sliding pin being 'visible when the parts of the gun are assembled, so that the operator may readily determine or ascertain the position of the shoulder 24 with reference to the shoulders 26. The shoulder 24 forms the connection between the trigger and the sear with which said shoulder is registered, and said sear is actuated by the shoulder 24 irrespective of the pawl 10, which is normally in its inoperative position when the hammers are cooked, said pawl serving only to operate the sear which is not in engagement with the shoulder 24.

In order to prevent the simultaneous dis-- charge of both barrels through the medium of the pawl 10 and shoulder 24, it is neces sary to provide some means for forcing the awl to its inoperative position during each break and close of the gun, and we therefore provide the cocking-lever 6 with a rearwardly-projecting arm 27, which extends throu h a slot 28 in the pawl and engages the shoulder 19, also formed upon the pawl in such osition that when the cocking-lever is rocked upwardly in the act of cooking the hammers the arm 27 simultaneously rocks the Fpawl to its inoperative position, as seen in gs. 2and 6.

In the operation of our invention, assuming that the hammers are in their cocked po- IIO sition, as seen in Fig. 2, at which time the v pawl 10 is thrown forward and the tri er is normal and it is desired to fire the righthand hammer first, then the pin 12 is shifted laterally to throw the shoulder 24 between the trigger and right-hand sear and out of alinement with the left-hand sear. Now when the triggeris pulled the right-hand sear is tripped to release the right-hand hammer, and during this operation the pawl 10 is elevated by the trigger to disengage the shoulder 16 from the detent 17. When this hammer is fired, the cam-face 20 operates upon the forward end of the sear to elevate the rear end of the sear to prevent en agement is operated to tri the other sear, it being understood that W en the trigger is held and the sp .iaif lh I rin 9 rocks the g awl 10 to its operative osition the shou der 14 is above the shoul er 15 of the left-hand sear and immediately upon the firing of the hammer, as described, the awl 10 is returned to its inoperative (position b T the recoil and its own inertia an may be eld in this position by the detent 17. Now if it is desired to fire the left-hand hammer it is necessary to draw the trigger back to disengage the shoulders 16 and 17 and then to release the trigger, so that the shoulder 14 may ride under the shoulder 15 of the left-hand sear, and when the trigger is again drawn back the left-hand sear is operated to release the left-hand hammer. B-oth hammers being now fired, it is desired to recock the same, which is done in the usual manner by breaking the gun to operate the cockinglever 6, which simultaneously returns the pawl lO'to its inoperative position ready for a repetition of the firing, as just described. If it is desired to fire the left-hand hammer first after each break and close of the gun, it is simply necessary to slid t P n 12 endwise to register the shoulder 24 W1 shoulder 26 of the left-hand sear.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, 1s
